Question

cam ABC is supported by a post at B. The coefficient of static friction between the post and the Beall at is g = 0.28. The coefficient of static friction between the post and the ground at Dis Ho = 0.21. The coefficient of kinetic friction between the post and the beam at Bis Ug = 0.20. The coefficient of kinetic riction between the post and the ground at Dis Ho - 0.17 a) Draw a free body diagram of beam ABC b) Draw a free body diagram of post BD c) Determine the value of force P which will cause the post to slip B d) Determine the value of force which will cause the post to slip D e) Determine the force that will cause the system to collapse f) Enter the answer for parte below 2516
